Supratentorial Craniotomies with or without Dural Closure-A Comparison.

Background: Dural closure is a routine surgical step in neurosurgery. The benefit of suturing the dura to achieve watertight closure-with or without the use of dural substitutes-has been questioned in supratentorial craniotomy. We performed a retrospective study to examine the possible benefits and harms of suturing the dura compared with no dural closure and the occurrence of postoperative infection, cerebrospinal fluid (CSF) leak, and postcraniotomy headaches.
